6.4.4
Degree of protection of the auxiliary terminal box
Normally the cable entry plate is supplied undrilled. In special versions the cable entry plate
can be supplied with tapped holes for connection of cable entries and conductor entries. This
requires derating of the IP degree of protection of the auxiliary terminal box.
1. Close the openings for operation, using suitable sealing elements such as sealing plugs,
threaded adapters, cable or conductor entries.
6.4.5
Connecting temperature monitoring for the stator winding
The stator winding is monitored for thermal loading by temperature sensors embedded in the
stator winding.
The connecting cables of the temperature sensors are routed to the main or auxiliary terminal
box, depending on the version. The connection and assignment of the terminals is specified
in the circuit diagram.
WARNING
Hazard due to electric shock
The installation of the temperature sensors for the winding monitoring with respect to the
winding is implemented according to the requirements for basic insulation. The temperature
sensor connections are located in terminal boxes, safe to touch, and have no protective
separation. This is the reason that in the case of a fault, a hazardous voltage can be present
at the measuring sensor cable. When touched, this can result in death, severe bodily injury
and material damage.
● When connecting the temperature sensor to external temperature monitoring devices,
when required, apply additional measures to fully comply with the requirements set out in
IEC 60664-1 or IEC 61800-5-1 "Hazard due to electric shock”.
6.4.6
Intrinsically safe circuits for sensors or probes
Observe standard GB 3836.15 when selecting and routing connecting cables.
NOTICE
Intrinsically safe circuits for sensors or probes
If blue connection terminals are installed for sensors, you must connect them to certified
intrinsically safe circuits. This can otherwise result in damage.
Ensure that you also observe the additional requirements in GB 3836.15 for intrinsically safe
equipment and the associated connecting cables.
